I don't really want to be a dick, but I have to agree with mountainbikinbryno, what kinda drugs/alcohol are you on? Or, can you just not read very well?
I hope that I have now made myself clear for you Reiko.

Sorry went from the first post read it and made an opinion... Didn't bother reading the rest...

Frank - I got when he was 8 and is now 10. He is a Shar Pei / Terrier mix. 50lbs Very strong and full of life, doesn't shed, he is the dummy of the group but very gentle and will not leave mine or my GF's side. This dog can leap over a 4' chain link fence from a stand still.

Sounds like Duke when I rescued him in Detroit from a burned out garage that had a van in it that he made his home... Love this dog to death... My brother has him now...

Irok is 39 lb.I got my parents a heeler and blue tick mix. She weighs 38 lb.cool mild dog.I grew up w labs me my sister and my parents all had a lab.my sister just got another black lab.its huge! Drools everywhere but is a good dog.after having a heeler I will never have a different breed.must get them as a puppy to train them how you want.never really talked to any heeler owner that said it wasn't there best friend.good luck with your choice.

Alright, you said you wanted an active dog, so I'm going to plead my case one last time. This'll be the last time I pimp my dog out.

He's 3/4 Blue Merle Australian Sheppard and 1/4 Australian Cattle Dog. He's 45lbs full grown. The most loyal dog I have ever had. Eats 2 cups a day.
I'm not a runner but when my little brother was staying with me on leave from the Army he would go running every morning and take Rocky with him. The dog just want's to go go go as you'll see in the link below. He's always by my side and so damn smart.
I know you have an issue with shedding, which he does but it is not as bad as a Golden or a pure bred Aussie because of the Cattle Dog in him.
The breeder we got him from is in Newyago and we actually ran into another pup from the same breeder at the Lake Orion dog park. I think the dogs share a parent.
